	// While other methods can be used to display an icon on the title bar of a JFrame,
	//  using 'getClass().getResource()' allows the graphic to be loaded and used directly
	//  from an executable (runnable) .JAR file if one is created for a Java program
	//  using a JFrame; without this approach, if making a .JAR file, the .CLASS file
	//  would first have to be extracted from the .JAR file before it would be able to
	//  read the icon graphic; note that this same technique applies to all graphics and
	//  sounds loaded from within .JAR files; note, also, that no path is given here, and
	//  the icon file needs to be in the same folder as the .CLASS file (the "bin" folder)
	//  in Eclipse, and then in the same folder as the .CLASS file if everything is put
	//  into a .JAR file; in addition, note that using a .ICO file does not seem to work
	//  here; the file appears to need to be in .GIF, .JPG, or .PNG format; finally, note
	//  that this line does not place the icon on the JFrame; it loads the image, but the
	//  icon is placed on the JFrame with the 'setIconImage(icon.getImage())' line below
	private ImageIcon icon = new ImageIcon(getClass().getResource("daveicon.gif"));
